2016 AUDI S8 wheel

Smart Techn olo gy
- Under certain climatic and operating condi­
tions such as passing through water, driving
in heavy rain or after washing the vehicle,
the effectiveness of the brakes can be re­
duced . In w inter, ice can accumulate on the
brake pads, linings, discs and drums . Care­
fully apply brakes fo r a tes t. Brakes w ill dry
and ice coatings wi ll be cleaned off after a
few careful brake applications .
- Driving for an extended pe riod of time on
salt-covered roads witho ut using your
brakes can also affect bra king efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few carefu l
brake applications.
- If you damage the front spoiler, or if you in­
stall a different spoiler, be sure the air flow
to the front brakes is not obstructed. Other­
wise the brake system could overheat reduc­
ing the effectiveness of the entire brake sys­
tem.
- Failure of one brake circuit will impair the
braking capability result ing in an increased
stopp ing distance. Avoid driving the vehicle
and have it towed to the nea rest Aud i dealer
or qualified workshop.
- Never let the vehicle roll to a stop with the
engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed considerably
harder to make up for the lac k of booster
assistance.
Electromechanical power
assist, dynamic steering
The electromechanical power assist helps the
driver when steering.
Power steering adapts electronically based on
the vehicle speed.

Driving with your
quattro
With All Wh eel Drive , all four wh eels are driven .
General information
With All W heel Drive, power is dis tribute d to all
four wheels . This happens automatically depend­
ing on your dr iving style and the road conditions
at the time . See also¢
page 190 . With the sport
d ifferent ial*, power d istr ibution to the rear
wheels is variable and can be adjusted with Audi
d rive select*
¢ page 106. Always read and fo llow
safety preca utio ns ¢ ,&. .
Winter tires
When drivi ng in the w inter, you r vehicle with All
Wheel Drive has an advantage, even with reg ular
tires. In winter road cond itions it may be adv isa­
b le to mount w inte r tir es (or a ll-season tires) for
i mproved d riveab ility and bra king : these tires
must be mounted on
all four wheels . See also
¢ page 251, W inter tires.
Snow chains
Where snow chains are mandatory on certain
roads, this normally also a pplies to vehicles w it h
All Whee l Dr ive ¢
page 251, Snow chains.
Replacing wheels /tires
Veh icles w ith All Wheel Drive must always have
tires of the same s ize. A lso avo id tires wi th d iffer­
ent tread depths. For detai ls see page
¢ page 243.
Off-Road driving?
Your Aud i does not have e nough g round clear­
a nce to be used as an off-road vehicle . It is there­
fore best to avoid rough tracks and uneve n ter­
r ain as m uch as possible . Also refe r to
¢page 197.
_& WARNING ,~ -
Always adjust you r driv ing to road and t raffic
conditions . Do not let the extra safety affo rd­
ed by All Wheel Drive tempt you into taking
extra risks.
Sma rt Technology
- Although the A ll Whee l Drive is very effec­
tive, always remember that braking capacity
is limited by t ire tract ion. You shou ld there­
fore not dr ive at excessive speeds on icy or
slippe ry road surfaces .
- On wet road surfaces, be careful not to dr ive
too fast because the front wheels could be­
g in to slide on top of the water (aquap la n­
ing) . If th is should oc cur, you will have no
warn ing from a sudden increase in engine
speed as with a front-wheel d rive vehicle.
Always d rive at speeds which are suited to
the road conditions -risk of c rash.
Energy management
Starting ability is optimized
Energy management controls the distribution of
electrical energy and thus op timizes the availa­
bility of electrical energy for starting the engine .
If a vehicle with a conventional energy system is
not driven for a long pe riod of time, the battery is
discharged by id ling curre nt consumers (e.g. im­
mobilize r) . In certain circumstances i t can resu lt
in t he re being i nsufficien t energy ava ilable to
sta rt the engine.
Intelligent energy manageme nt in you r vehicle
hand les the distribution of electrical energy .
Start ing ability is markedly improved and the life
of the ba ttery is ex tended.
Bas ica lly, energy management cons ists of
bat ­
tery diagnosis , idling current management
and
dynamic energy management .
Battery diagnosis
Battery d iagnosis continuously dete rm ines the
state of the battery. Sensors determine battery
vo ltage, battery current and battery tempera­
tu re. This de termines the current state o f ch arge
and the power of the battery .
Idling current management
Idling current management reduces energy con­
sumption while the vehicle is standing. With the ..,_

conditions are unfavorable - particularly when
going downhill.
Red uce veh icle speed
imm ediatel y if the tra ile r
shows the s lightest sign of swaying.
Do not try
to stop the sway in g b y accele rating .
Observe speed lim its . In some areas, speeds for
ve hicl es towing tra ilers are lower than for reg ula r
veh icles.
A lways apply brakes early . When dr iving down­
h ill , sh ift into a lower gear to use the engine
b raking effect to slow the veh icle. Use of the
brakes a lone can cause them to overheat and fail.
Air suspension*
When driving with a tra iler, activate the trailer
mode of the air suspension . Switch the air sus­
pens ion tra iler mode on when you a re towing a
tra ile r. This will limit the regulat ion by the air
suspens ion while driving . Select in the MM I:
ICARI function button > (Car )* sys tem s control
button >

On .
Coolant temperature
The coolan t temperature gauge¢ page 10 must
be observed carefully. The coo lant temperature
can increase if you drive on long inclines in a low
gear at high engine speeds. Reduce your speed
immed iate ly if the LEDs in the top part of the dis­
p lay turn on.

A WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent. Never let anyone ride in your car who is
not properly wearing the restraints provided
by Audi.
Trailer mode notes
Important to know
Your vehicle hand les different ly when towing a
trai ler because of the additiona l weight and dif­
ferent weight distr ibut ion. Safety, performance

-
and economy will g reatly depend on how carefu l­
l y you load your trai ler and operate your rig .
Befo re yo u actually tow yo ur t railer, pract ice
turning, stopping and backing up in an area away
from traffic. Keep practicing unti l you have be ­
come complete ly familiar with the way your vehi­
cle-tra iler combination behaves and responds .
Backing up is diff icult and requ ires practice.
Backing up with a trailer genera lly req uires steer ­
ing action opposite to that when backing up your
vehicle witho ut a trailer .
Maintain a greater distance between yo ur vehicle
and the one in front of you. You will need more
room to stop . To compensate for the trailer, you
will need a larger than normal turning radius .
When passing, remember tha t you canno t accel­
erate as fast as you normally wou ld because of
the added load . Make sure you have enough room
to pass. After passing, allow p lenty of room for
your trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane changes.
(D Tips
- Do not tow a trailer du ring the break-i n pe ri­
od of your vehicle.
- If you tow a tr aile r, your A udi may requi re
more frequent ma intenance due to the ex­
tra load ¢

Parking on a slope
Do not park on a slope with a trailer . If it cannot
be avoided, do so only after doing the following:
When parking:
.,. App ly the foot brake.
.,. Have someone p lace chocks unde r both the ve­
hicle and the trailer wheels .
.,. With chocks in place, slowly release the brakes
until the wheel chocks abso rb the load .
.,. Turn the whee ls towards the curb.
.,. App ly the parking brake .
.,. Select the P selector lever posit ion.

When restarting after parking:
"'Apply the foo t brake.
"' St art the engi ne .
"' Se lect the D selector leve r position.
"' Release the parking brake an d slow ly pull out
and away from t he wheel choc ks .
"' Stop and have someone retrieve t he wheel
chocks .
(D Tips
If you move the selector lever of the a utomat­
ic transm ission to P before applying t he park­
ing brake and before block ing t he wheels, you
may have to use mo re force late r to move t he
lev er out of th e P position .

& WARNING
-Only wash the vehicle when the ignition is
off and follow the instructions from the car
wash operator to reduce the risk of acci­
dents.
- To reduce the risk of cuts, protect yourself
from sharp metal components when wash­
ing the underbody or the inside of the wheel
housings.
-After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the winter . The brakes
must be dried first with a few careful brake
applications.
{[) Note
-If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Power folding exterior mirrors* must only
be folded in and out using the power folding
function.
- To prevent paint damage, do not wash the
vehicle in direct sunlight.
-
Care and cleaning
-To reduce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges or similar items.
- Matte finish painted vehicle components:
- To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
- Never use car wash cycles that apply pro­
tective wax. It can destroy the matte fin­
ish effect.
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint. The paint could be damaged
when the stickers or magnets are re­
moved .
@ For the sake of the environment
Only wash the vehicle in facilities specially de­
signed for that purpose. This will reduce the
risk of dirty water contaminated with oil from
entering the sewer system.

Wheels and Tires
General information
~check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
~ If driving over curbs or similar
obstacles, drive slowly and ap ­
proach the curb at an angle.
~ Have faulty tires or rims re­
placed immediately.
~ Protect your tires from oil,
grease and fuel.
~ Mark tires before removing
them so that the same running direction can be maintained if
they are reinstalled .
~ Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as possible.
(i}) Note
-Please note that summer and
winter tires are designed for
the conditions that are typical i n those seasons. Audi recom­
mends using winter tires dur­
i ng the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
236
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be used in winter driving condi­
tions. The surface of the r ims
does not have sufficient corro­
sion protection for th is and
could be permanently dam­
aged by road salt or similar
substances.
